OKpowdah Posted January 22, 2013 Share Posted January 22, 2013 I'm just looking more into this now, but just wanted to kick this off ... With an amplitude of 4.5 on January 20 (the latest day in the data file), the GWO is currently at the 8th greatest amplitude on record (of 20,109 days) that began in 1958. And the 5th highest amplitude cycle on record. The four cycles ahead of this one were from November 2002, March 2005, January 1983, and January 2006 Link to comment Share on other sites More sharing options...
am19psu Posted January 22, 2013 Share Posted January 22, 2013 MJO wave is for real, son Link to comment Share on other sites More sharing options...
OKpowdah Posted January 22, 2013 Author Share Posted January 22, 2013 MJO wave is for real, son lol, seriously. Three of the four cycles ahead of this one were notable El Ninos. 2006 was a La Nina, but interestingly had a major stratospheric warming coincide with the MJO/GWO cycle ... the whole thing practically perfectly in sync with the current evolution.

Amped Posted January 23, 2013 Share Posted January 23, 2013 Most of the Mountain torque is from South America. Wonder how much of a difference it makes in the Northern Hemisphere? Link to comment Share on other sites More sharing options...
CoastalWx Posted January 23, 2013 Share Posted January 23, 2013 All those years had some good events down the road from those dates too. Impressive stuff. That's a sh*t load of westerly momentum being added. Link to comment Share on other sites More sharing options...

Met1985 Posted January 23, 2013 Share Posted January 23, 2013 Nice stuff on here. Learning everyday from the Mets on this board. Thanks! Link to comment Share on other sites More sharing options...
HM Posted January 23, 2013 Share Posted January 23, 2013 Most of the Mountain torque is from South America. Wonder how much of a difference it makes in the Northern Hemisphere? Two things: 1. The NH has contributed to the surge (outside of N. America, so far) and there is frictional dissipation going on (due to the MJO) in the Subtropical-Tropical C PAC. 2. These all contribute to the global budget, length of day etc. so the SA MT is important, just like any other area of the world. But in terms of the Pacific Jet and CONUS teleconnections, its connection is obviously looser. Link to comment Share on other sites More sharing options...
